I don't think so, I tried digging into setting a while back to see if I could find anything. I also wanted YouTube to have a play all feature in my sub box, so I could watch all my subs continuously, but eh...
That's so upsetting.
I was really wanting to showcase my friends videos. I really appreciate you taking the time to drop an answer for me though, and help. Take note @TeamYouTube we don't want to advertise your over watched videos. We want to help our friends.
